It's not just RFC 2396 that's involved here. It's HTTP. Without 
appending the / you can;t even make the request to the web server. 
That is, HTTP does not allow you to say:

GET HTTP/1.0

You have to say

GET / HTTP/1.0

The problem is that the HTTP client makes this change, so the 
document returned does indeed have the proper base URI of 
http://www.cafeconleche.org/. The problem is when the parser does not 
use the actual base URI of the document to resolve the relative URIs 
in that document. Instead it uses the original request URI. The HTTP 
client part of the code changed this URI, but the XML parser's view 
of the URI did not change in sync.
